• Wüstite - Wikipedia

    en.wikipedia.org/wiki/W%C3%BCstite According to Vagn Fabritius Buchwald, wustite was an important component during the Iron Age to facilitate the process of forge welding. In ancient times, when blacksmithing was performed using a charcoal forge , the deep charcoal pit in which the steel or iron was placed provided a highly-reducing, virtually oxygen-free environment, producing ...

  • Wurtzite - Wikipedia

    en.wikipedia.org/wiki/Wurtzite Wurtzite is a zinc and iron sulfide mineral ((Zn,Fe)S), a less frequently encountered structural polymorph form of sphalerite.The iron content is variable up to eight percent. It is trimorphous with matraite and sphalerite.. It occurs in hydrothermal deposits associated with sphalerite, pyrite, chalcopyrite, barite and marcasite.It also occurs in low-temperature clay-ironstone concretions.

AB - The high‐temperature electrical conductivity in Fe1−xO is analyzed at constant thermoelectric coefficient rather than at constant x. Small polaron conduction is p‐type with an activation energy of 15.4 kJ/mole (0.16 eV), independent of composition.

    www.sciencedirect.com/science/article/pii/S1566736719303681 In this work, surface properties of wustite-based iron and iron‑cobalt catalysts were investigated. Measurements of hydrogen temperature-programmed desorption (TPD-H 2) and surface area of active forms of catalysts were conducted after reduction of catalyst precursors (16 h) in pure hydrogen at various temperatures (450, 475, 500, 550 and 600 °C).
